UMC Shetland Sheepdog Lance Canine Tooth Study
SAMPLE HANDLING
For Canine DNA Research at the University of Missouri
Blood Sample - The ideal sample for DNA extraction is 5 to 10cc's of whole blood, in purple-topped (EDTA) tubes
(one or several, depending on tube size). For very small dogs, 3ccs should be sufficient. More volume will yield more DNA, so in
this situation, a larger sample is appreciated. The blood sample needs only to be put in the tubes and rocked gently a few
times to distribute the anticoagulant - do not spin, extract serum, or do anything further. Refrigerate if the sample is being held for
any time before shipping, but do not hold the sample longer than 1 week before shipping or it may become unusable.
Frozen Semen - If there is frozen semen stored from sires or affected dogs, DNA can be extracted from it. Please
send 1 straw or 5-7 pellets. They do not need to be shipped frozen, but do pack them in a crush-proof & leak-proof container.
Tissue Sample - DNA can be extracted from any cell-rich tissue. If a dog is to be tested post-mortem, a 1" cube (or
equivalent) of tongue, other muscle, spleen, kidney, or liver will provide a large amount of DNA (one tissue is sufficient - do not
send multiple tissues). Tissue samples should be placed in a clearly labeled freezer bag or other sterile container and frozen.
DO NOT place in formalin! Place the bagged tissue inside another bag, freeze, and ship with a frozen cool pack (do not use dry
ice, or ice cubes placed in a ziplock bag).
Label sample with the following:
Dog’s call name - Owner's last name
(If samples from several dogs are sent together, number samples and forms)
Both pages of the Individual Dog Information Form & Survey that follow this instruction sheet should be completed,
and a pedigree copy, if available, should be included with the sample. If no pedigree information is available, please indicate this
on the survey page. PLEASE take the time to complete the survey form - this information is very important for the ongoing
research.
Shipping - Ideally the sample should be shipped immediately (with a tissue sample make certain it is completely frozen
first). If samples are held for a day or over a weekend, blood must be refrigerated, and tissue samples must be kept frozen. Ship
via overnight delivery (FedEx, US Mail-Express service, or UPS). Do not send on a Friday - there will not be anyone
to accept the delivery on a weekend, and the sample could be unusable by Monday. Pack in a small insulated container (most
vets have these for shipping samples to labs), with one or more cool packs - it is important that blood samples be kept cool but
not frozen, and tissue samples be kept as frozen as possible.

The above dog is affected – unaffected (please circle one) and check the appropriate boxes below.
If affected, please complete the section below:
The upper canine tooth was “lance” in relation to the lower canine tooth, i.e., its tip is located in front of the lower canine tooth rather
than behind it.
Right upper canine tooth affected

Information concerning other dental anomalies may be used in additional studies concerning teeth. Please check appropriate boxes below:
 I’d rather not complete the section below concerning other tooth problems or don’t think I can do so accurately. (Please skip to the section
about photographs and complete the remainder of the survey form.)
 Other than the above noted lance canine tooth abnormality, this dog has normal, complete dentition.

(Note: There are 4 premolar (PM) teeth with each subsequent tooth being larger than the one in front of it. In some dogs in which the adult 2nd
PM tooth is absent, the “baby” tooth is retained. In a dog over 7 mos. of age, retention of the baby 2nd PM tooth can be confirmed if the 2nd PM
tooth is not larger than the 1st.)

 Close-up photographs (either hard copy or jpg format) of the above dog’s incisor and canine teeth are included with this form or
e-mailed to: Liz Hansen at: [email protected]. (If possible, please include views of the premolar teeth of the right and left sides.)
Pedigree (family tree) information is very helpful for this research, and is held in complete confidence by the researchers. Please
enclose a pedigree copy or a copy of the registration certificate with this survey.
Pedigree enclosed
Pedigree will be mailed or emailed separately
Pedigree unknown/not available
I submit this sample and pedigree for the purpose of DNA testing; I understand that DNA left over following the test may be stored for potential future research; I
understand that the results of this test will be reported only to the owner listed on this form and to the veterinarian (if requested) listed here, via email or FAX; and
I have supplied complete and accurate information, to the best of my knowledge.
